Description

Technical Field

[0001] This utility model relates to the field of tobacco packaging technology, and in particular to a packaging machine with the function of cutting transparent paper from cigarette boxes. Background Technology

[0002] During the packaging of cigarettes, transparent paper is typically used to wrap the cigarette cartons to prevent the cartons and the cigarettes inside from getting damp. After the transparent paper roll is unrolled, a new roll of transparent paper needs to be joined with the original roll remaining on the packaging machine to ensure the orderly progress of the packaging work. Before joining, the remaining transparent paper on the conveyor path and the unrolled transparent paper roll must be cut and separated. Currently, this is usually done manually, with one hand holding a paper cutter and the other holding the transparent paper, and then directly scraping the transparent paper to make a cut. This method often produces skewed cuts with low flatness, affecting the smoothness of the joint. During subsequent packaging, paper jams and blockages frequently occur at the joint, increasing the downtime of the packaging machine and making it difficult to guarantee the packaging efficiency of the cigarette cartons.

[0025] The following is combined Figures 1-4 This invention provides a detailed description of a packaging machine with the function of cutting transparent paper for cigarette boxes, through specific embodiments and application scenarios.

[0026] like Figure 1 As shown, this utility model provides a packaging machine with the function of cutting transparent paper for cigarette boxes, including: a frame 1, a cutting mechanism 2, a first conveying roller 3, a second conveying roller 4, and an unwinding roller 5. The unwinding roller 5 is fitted with a transparent paper roll 100. The unwinding roller 5 is rotatably mounted on the frame 1 and is used to drive the transparent paper roll 100 to unwind. The first conveying roller 3 and the second conveying roller 4 are sequentially installed on the frame 1 and are used to convey the transparent paper 101 unwound from the transparent paper roll 100 to the packaging station. The cutting mechanism 2 is located between the unwinding roller 5 and the first conveying roller 3.

[0027] The cutting mechanism 2 includes a paper cutter 21 and a mounting base 22. The mounting base 22 is mounted on the frame 1. The side of the mounting base 22 has a feed hole 221 for the transparent paper 101 to pass through. The top surface of the mounting base 22 has a cutting hole 222. The cutting hole 222 extends along the width direction of the transparent paper 101. The paper cutter 21 is slidably disposed in the cutting hole 222 so as to cut the transparent paper 101 after the transparent paper roll 100 has been unwound.

[0028] Specifically, such as Figure 1 As shown, a roll of transparent paper 100 is fitted onto an unwinding roller 5. During rotation, the unwinding roller 5 unwinds the roll of transparent paper 100. A first conveyor roller 3 and a second conveyor roller 4 are both mounted on the frame 1 and sequentially positioned downstream of the unwinding roller 5 along the conveying path of the transparent paper 101. The transparent paper 101 is sequentially placed on the first conveyor roller 3 and the second conveyor roller 4, and is conveyed by the first conveyor roller 3 and the second conveyor roller 4 to the packaging station for packaging cigarette cartons.

[0029] After the transparent paper roll 100 is unwound, the transparent paper roll 100 and the transparent paper 101 laid on the conveyor path need to be cut apart so that the staff can replace the new transparent paper roll 100 and connect the end of the new transparent paper roll 100 to the original transparent paper 101 on the conveyor path to ensure the orderly progress of the packaging process.

[0030] like Figure 1 As shown, the cutting mechanism 2 is fixedly mounted on the frame 1 and positioned between the unwinding roller 5 and the first conveyor roller 3. Transparent paper 101 passes through the feed hole 221 and rests on the roller surfaces of the first conveyor roller 3 and the second conveyor roller 4, respectively. The cutting hole 222 is located above the transparent paper 101. Figure 2 As shown, the cutting hole 222 is a strip-shaped hole. The axial direction of the strip-shaped hole is parallel to the width direction of the transparent paper 101. When it is necessary to cut the transparent paper 101, the user operates the paper cutter 21, causing the paper cutter 21 to slide along the axial direction of the cutting hole, thereby cutting the transparent paper 101. Due to the tensioning effect of the unwinding roller 5 and the first conveying roller 3 on the transparent paper 101, the paper cutter 21 has strong stability when cutting the transparent paper 101, the transparent paper 101 is not easy to slip, the cut edge is consistent with the width direction of the transparent paper 101, and its flatness can be guaranteed.

[0031] This utility model provides a packaging machine with the function of cutting transparent paper for cigarette boxes. The unwinding roller 5 is rotatably mounted on the frame 1 and is used to drive the transparent paper roll 100 to unwind. The first conveying roller 3 and the second conveying roller 4 are rotatably mounted on the frame 1 in sequence and are used to convey the transparent paper 101 unwound from the transparent paper roll 100 to the packaging station so that the transparent paper 101 can pack the cigarette boxes. The mounting base 22 is located between the first conveyor roller 3 and the second conveyor roller 4. The transparent paper 101 passes through the feed hole 221 and rests on the roller surfaces of the first conveyor roller 3 and the second conveyor roller 4. The top surface of the mounting base 22 has a cutting hole 222, which extends along the width direction of the transparent paper 101. When the transparent paper roll 100 is unwound and needs to be cut, the user operates the paper cutter 21 to cut along the width direction of the transparent paper 101, so as to ensure the flatness of the cut edge of the transparent paper 101. During the packaging process, it is not easy to jam or block paper, thus ensuring the packaging efficiency of cigarettes. Moreover, due to the tensioning effect of the unwinding roller 5 and the first conveyor roller 3 on the transparent paper 101, the user does not need to hold the transparent paper 101 by hand during the cutting process, which simplifies the cutting operation. The cut edge is not easy to be crooked, which improves the convenience of changing the transparent paper roll 100.

[0032] Furthermore, in some embodiments, such as Figure 2 , Figure 3 and Figure 4 As shown, the mounting base 22 is provided with a clamping plate 23 corresponding to the cutting hole 222. The length direction of the clamping plate 23 is aligned with the width direction of the transparent paper 101. The clamping plate 23 is movably disposed in the feed hole 221 and is used to press the transparent paper 101 against the hole wall of the feed hole 221 after the transparent paper roll 100 is unwound.

[0033] Specifically, such as Figure 3As shown, the clamping plate 23 is located inside the feed hole 221. Transparent paper 101 passes through the feed hole 221 and is positioned between the hole wall and the clamping plate 23. As the clamping plate 23 moves upward, it pushes the transparent paper 101 against the hole wall of the feed hole 221, thus clamping the transparent paper 101 between the hole wall and the clamping plate 23. This ensures that the transparent paper 101 is less likely to slip or skew during cutting, improving the flatness of the cut. The length direction of the clamping plate 23 is aligned with the axial direction of the cutting hole 222 to ensure that the hole wall of the feed hole 221 and the clamping plate 23 can clamp the transparent paper 101 throughout its width, ensuring a flat cut and preventing paper jams or blockages during packaging, thereby improving the packaging efficiency of the cigarette pack.

[0034] In some embodiments, the cutting mechanism 2 further includes an adjusting member and an elastic member. The elastic member abuts against the walls of the clamping plate 23 and the feed hole 221, respectively. The mounting base 22 has a threaded hole. The axial direction of the threaded hole is aligned with the axial direction of the elastic member.

[0035] The outer wall of the adjusting member has an external thread that matches the threaded hole. The adjusting member passes through the threaded hole. As the adjusting member is screwed in, the inner end of the adjusting member pushes the clamping plate 23 against the wall of the feed hole 221.

[0036] The elastic element can be a spring. The adjusting element can be a screw. One end of the spring is fixedly connected to the wall of the feed hole 221, and the other end is fixedly connected to the side of the clamping plate 23 opposite to the transparent paper 101. A threaded hole is located at the bottom of the mounting base 22. The screw passes through the threaded hole. When it is necessary to cut the transparent paper 101, the screw is rotated. As the screw is screwed in, the inner end of the screw pushes against the clamping plate 23, causing the clamping plate 23 to move upward until it abuts against the wall of the feed hole 221 on the opposite side. This achieves clamping of the transparent paper 101 by the wall of the feed hole 221 and the clamping plate 23, ensuring the stability of the paper cutter 21 when cutting the transparent paper 101. When packaging cigarette boxes, simply rotate the screw in the opposite direction to move it away from the pressure plate 23. The pressure plate 23 will then return to its original position under the elastic action of the spring, allowing the transparent paper 101 to pass through the feed hole 221. This ensures that the first conveyor roller 3 and the second conveyor roller 4 can convey the transparent paper 101 to the packaging station.

[0037] In other embodiments, such as Figure 4 As shown, the cutting mechanism 2 also includes a connecting plate 24. The two ends of the clamping plate 23 are respectively fixedly connected to a first mounting rod 25 and a second mounting rod 26 arranged in parallel. The first mounting rod 25 and the second mounting rod 26 are slidably inserted into the mounting base 22. The connecting plate 24 is fixedly connected to the ends of the first mounting rod 25 and the second mounting rod 26 away from the clamping plate 23.

[0038] Specifically, such as Figure 4 As shown, the inner ends of the first mounting rod 25 and the second mounting rod 26 are fixedly connected to both ends of the clamping plate 23, respectively. The bottom of the mounting base 22 has a first through hole and a second through hole. The first mounting rod 25 and the second mounting rod 26 are slidably inserted through the first through hole and the second through hole, respectively. The outer ends of the first mounting rod 25 and the second mounting rod 26 are fixedly connected to the connecting plate 24, respectively. The connecting plate 24 is located below the mounting base 22. Thus, when it is necessary to cut the transparent paper 101, the connecting plate 24 is pushed upward, so that the clamping plate 23 abuts against the hole wall on the opposite side of the feed hole 221, thereby achieving the clamping of the transparent paper 101 by the hole wall of the feed hole 221 and the clamping plate 23. When it is necessary to package the cigarette box, it is only necessary to push the connecting plate 24 downward, so that the clamping plate 23 returns to its original position.

[0039] Furthermore, in some embodiments, such as Figure 4 As shown, the cutting mechanism 2 also includes a handle 27. The handle 27 has a connecting rod 271. The connecting plate 24 has a groove 241. One of the groove walls of the groove 241 and the connecting rod 271 has a locking head, and the other has a locking slot. The locking head is engaged with the locking slot. The connecting rod 271 is slidably inserted through the mounting base 22 and is arranged parallel to the first mounting rod 25.

[0040] Specifically, the handle 27 includes a connecting rod 271 and a handle. The outer end of the connecting rod 271 is fixedly connected to the handle, or the connecting rod 271 and the handle are an integral structure. The handle 27 is provided to facilitate the user's grip. Optionally, the outer wall of the connecting rod 271 is provided with a groove, and the groove wall of the groove 241 is provided with a locking head. The locking head is engaged with the groove, thereby achieving a fixed connection between the connecting rod 271 and the connecting plate 24. The bottom of the mounting base 22 is provided with a third through hole. The inner end of the connecting rod 271 is slidably inserted through the third through hole. When it is necessary to cut the transparent paper 101, the user holds the handle and pushes the connecting rod 271 upward. The connecting rod 271 drives the first mounting rod 25 and the second mounting rod 26 to slide upward, thereby causing the clamping plate 23 to abut against the hole wall on the opposite side of the feed hole 221, thereby achieving clamping of the transparent paper 101 by the hole wall of the feed hole 221 and the clamping plate 23. When it is necessary to repackage the cigarette pack, simply hold the handle and pull down the connecting rod 271 to return the clamping plate 23 to its original position.

[0041] Specifically, the paper cutter 21 includes a fixedly connected handle 211 and a blade. The blade is slidably inserted through the cutting hole 222. A first guide rail 28 and a second guide rail 29 are fixedly mounted on the top surface of the mounting base 22. The extending directions of the first guide rail 28 and the second guide rail 29 are consistent with the extending direction of the cutting hole 222, and they are located on opposite sides of the cutting hole 222, respectively. The opposite ends of the handle 211 are slidably disposed on the first guide rail 28 and the second guide rail 29, respectively.

[0042] The handle 211 and the blade are fixedly connected. The blade is fixed to the center of the bottom of the handle 211, so that a first stepped surface and a second stepped surface are formed at the connection between the handle 211 and the blade. The first guide rail 28 and the second guide rail 29 are arranged in parallel and located on opposite sides of the blade. The first stepped surface and the second stepped surface are in sliding contact with the first guide rail 28 and the second guide rail 29, respectively, so as to guide the paper cutter 21 to slide along the axial direction of the cutting hole 222 through the first guide rail 28 and the second guide rail 29, further ensuring the flatness of the cut of the transparent paper 101.

[0043] In some embodiments, the handle 211 has a contoured groove 2111. The contoured groove 2111 conforms to the shape of a human finger, thereby facilitating the user's grip and improving the ease of cutting the transparent paper 101.

[0044] Furthermore, in some embodiments, the groove wall of the contour groove 2111 is provided with anti-slip texture. The anti-slip texture can increase the friction between the handle 211 and the user's fingers, reduce the risk of the fingers slipping off the handle 211 during the cutting process, and improve the safety of the user when operating the paper cutter 21.

[0045] In some embodiments, the packaging machine with the function of cutting the transparent paper of cigarette boxes further includes a fastener 6. A mounting base 22 is detachably mounted on the frame 1. The mounting base 22 is provided with a connecting lug 220. The connecting lug 220 has a first connecting hole. The frame 1 has a second connecting hole. The fastener 6 passes through the first and second connecting holes to lock the mounting base 22 to the frame 1.

[0046] The connecting lug 220 and the mounting base 22 can be an integral structure. Optionally, the fastener 6 is a bolt or screw. When the cutting mechanism 2 needs to be installed, the fastener 6 passes through the first connecting hole and the second connecting hole in sequence to fix the connecting lug 220 to the frame 1, thereby achieving a stable connection between the mounting base 22 and the frame 1. When the cutting mechanism 2 needs to be disassembled, the fastener 6 only needs to be unscrewed from the first connecting hole and the second connecting hole to separate the mounting base 22 from the frame 1. The mounting base 22 and the frame 1 are detachably connected, allowing users to choose whether to install the cutting mechanism 2 according to actual needs, thereby improving the overall ease of use of the packaging machine.

[0047] In some embodiments, such as Figure 1 As shown, the packaging machine with the function of cutting cigarette box transparent paper also includes a drive unit. The drive end of the drive unit is connected to the unwinding roller 5.

[0048] The frame 1 includes a main body 11, a first rod 12, a second rod 13, and a connecting shaft 14. The two ends of the first conveyor roller 3 are rotatably mounted to the first rod 12 and the second rod 13 via bearings, respectively. The first rod 12 and the second rod 13 are fixed to the connecting shaft 14. The connecting shaft 14 is hinged to the main body 11. A pressure sensor is fixedly mounted on the main body 11 near the first rod 12. The pressure sensor and the drive unit are communicatively connected.

[0049] Specifically, both ends of the connecting shaft 14 are hinged to the main body 11. The bottom ends of the first rod 12 and the second rod 13 are fixed to both ends of the connecting shaft 14. Alternatively, the first rod 12 and the second rod 13 are integrally formed with the connecting shaft 14. The two ends of the first conveyor roller 3 are rotatably connected to the top ends of the first rod 12 and the second rod 13 via bearings. The pressure sensor is fixed to the main body 11 and located beside the first rod 12. The transparent paper 101 overlaps the roller surface of the first conveyor roller 3.

[0050] The packaging machine with the function of cutting transparent paper for cigarette boxes provided by this utility model also includes a controller. The pressure sensor and the controller are communicatively connected, and the controller and the drive unit are communicatively connected, thereby realizing communication between the pressure sensor and the drive unit. When the packaging component at the packaging station is working, the transparent paper 101 is pulled upwards, and the transparent paper 101 is in a taut state. The transparent paper 101 drives the first conveyor roller 3 to swing in the direction close to the pressure sensor, causing the first rod 12 to contact the pressure sensor. After sensing the pressure applied by the first rod 12, the pressure sensor sends a trigger signal to the controller. The controller controls the movement of the drive unit based on the trigger signal, and the drive unit drives the unwinding roller 5 to rotate, thereby realizing the automatic unwinding of the transparent paper roll 100. No unwinding switch is required, simplifying operation and improving the overall ease of use of the packaging machine. Optionally, the drive unit is a stepper motor or a servo motor.

[0051] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
